Safety Effectiveness of Regulatory Headlights Signs in Wyoming (Phase 1 and Phase 2)

This project shall perform a synthesis of existing research studies of the dynamic message signs safety benefits; identify and rank hotspot locations of lane departure crashes, head-on and opposite sideswipe crashes on Wyoming roadways; evaluate the safety effectiveness of daytime running lights using Wyoming crash data for daytime running lights equipped and non daytime running lights vehicles, and motorcycles; conduct a field study on current headlight signed hotspot locations to collect data about the compliance of daytime running light use and the newly 24-hour low beam lights in newer vehicles; develop a plan for state wide sign implementation; conduct a cost/benefit analysis; conduct a driver simulation experiment; field test the experiment; and finalize statewide implementation and cost/benefit analysis.
